1991 4Runner-Engine dies when it gets hot

I have replaced all plugs and wires rotor and cap... I also put in a new coil. It ran and kept running perfect for about a month and a half after I replaced the coil. I bought a new one from Autozone. Maybe the new coil went bad already? Need some ideas.. guys help me out!? Also what is the name of the box right behind the coil? I cant think of it...thanks!

Hi! Well lets see....when I replaced the coil it seems to be fine. we took it all day around town so it got nice and hot and it still starts just fine. Is there a way to test the ignigter? I was told there wasn't. Is there anything that can make the coil burn out? Maybe I just got a bad coil....what do you think? Thank you ... Ireally appreciate it!! Hi!

The Honda system uses a coil that mounts inside the dist, right ?If you can check voltage output at the coil tower with the cap off you can find out if the coil is firing. If it is, then yes the rotor could be the problem. The voltage has to go thru the cap to the center of the rotor then to each plug terminal. The spark can jump thru the rotor and ground thru the dist shaft.

Check for an air leak in the fuel system. It sounds like the son-in -law did good work but missed an air leak somewhere. The system is not providing enough fuel to the engine. The other possibility is that you are pulling a vacuum on the fuel tank. They have to be vented either through the cap or through the canister. First take the fuel cap off and see if the truck will run. If it does put the fuel cap back on and pull the hose off the canister and try to run the truck. If it runs it was the canister.

while engine is running grab the wire harness that leads into the distributor housing with a pair of needle nose pliers and wiggle the wires!!
if the engine stumbles or stalls that is your prob!!!
go to parts store and get a magnetic pickup assembly!!
i think they call it something else but its the same concept, just different because it's a dodge thing!!!

Hello;
Take the distributor cap off, and turn the engine over. Does the rotor turn? Then pull the #1 spark plug and with your finger over the spark plug hole , tap the engine over to top dead center. See where the rotor is pointing. Also check to ensure your points are opening and closing. With an ohm meter make sure you have continuity through the carbon for the coil in the cap. Hope it helps.

I had the same problem with my 85 cj7 this week, I relpaced the ignition control module, plugs, wires, cap, rotor and the the coil; still had no fire to plugs. the problem turned out to be my distributor, replaced it today and she fired right up. Most likely it was the pick up module in the distributor that went bad.
